Paid but disconnected

I made the below payment on 26/05/2015. My wife went to your store in Norwood on 27/05/2015 and furnished this very same POP and was told she would be activated in 2 to 24 hours. I was reconnected on 28/05/2015. I have just been suspended again for no reason. I went to you store in Norwood this morning and enquired as to the reason. I was told that they would send this to the creditors department and call me back, I went to the store at 09:38. I have called the store 8 times with nobody picking up. The service from MTN has been beyond shocking. I have sent a follow up mail with no response. I am a cell c customer as well and I have heard about their special deals to port to their network, I can say that their service is exceptional compared to the pathetic service I am getting from MTN.
